I just added an example in our resource center that shows that Curl is a gentle slope language. It is a markup, procedural, scripting and an object oriented language.
To demonstarte it I choose to draw a UPC bar code. Note that in the code I have used flowing text, markup, procedures and objects. This example shows how these things can all be done so seamlessly in Curl.
I have implemented the UPC bar code using two techniques. The first technique uses Rule objects to draw the bars of the bar code. The second technique is more efficient but needs more expertise. It uses the rendering APIs to render the bars of the bar code.
Example: Gentle Slope.
